"Bachelorette" Rachel Lindsay's season is just getting underway but a number of her rejected guys will soon be heading to a tropical destination to film "Bachelor in Paradise."

The summer spinoff is rumored to be filming in Mexico and, once again, host Chris Harrison will be standing in the sand to welcome guys and girls from past seasons of "The Bachelor" and "The Bachelorette."

When does the beach-front drama begin?

According to ABC, the "Bachelor in Paradise" Season 4 premiere will air on Tuesday, August 8, one day after "The Bachelorette" season finale. Just like last season, the show will move to a two-night format starting with week two.

The remaining episodes will air from 8 - 10 p.m. on Monday nights and from 8 - 9 p.m. ET on Tuesday nights. There is no word (yet) whether or not the network will revive the live After Paradise talk show.

Who's heading to 'Paradise' this summer?

ABC will keep the cast list a secret for as long as they can. However, that doesn't mean the names of the contestants won't leak out online. So far, Raven Gates is the only person who has been confirmed for the show. But it's a no-brainer that Corinne Olympios will join her in "Paradise" along with the other ladies who showed up on the "Bachelorette" premiere last week — Alexis Waters, Jasmine Goode, Kristina Schulman, Whitney Fransway, and Astrid Loch.

Other girls rumored to be joining the cast include Sarah Venal (Nick's season), and at least two girls from Ben Higgins' season – Danielle Maltby and Danielle Lombard.

Many of the guys from JoJo's season are rumored to be joining the cast. They aren't keeping their desire to be on the show a secret, either. Robby Hayes, Luke Pell, and Chase McNary are expected to be part of the Season 4 cast.

And Robby is dropping strong hints that he'll be there, posting an Instagram pic with producer Elan Gale that just screams, "We'll see you in 'Paradise'!"

Fans can expect to see several guys from Rachel's season of "The Bachelorette" stir up some drama this summer. Rumored names include Dean, Kenny, Blake E., and that ever-so-annoying Lucas "Whaboom" Yancey.

In addition to the guys and girls from the most recent seasons of "The Bachelor" and the "The Bachelorette," there's always the possibility that cast members from previous seasons of "Bachelor in Paradise" will come back for a second shot at finding love. Will we see Jared Haibon, Amanda Stanton, Josh Murray, or Ashley Iaconetti bring some drama to the new season?

Mark your calendar now — "Bachelor in Paradise" returns at 8 p.m. ET on August 8.
